I read an article last year that said you should align the spine on your arrows so that the fletching is the same. It described floating the bare shafts in a tub and then marking the side that was up. Then you glue your fletchings on and align the nocks. This will get the arrows to bend the same way when the bow applies force to them.

Have any of you heard of this?
Do any of you do this?
If yes, have you seen a marked improvement in arrow flight?

Just curious. Thanks.
